Black Bear and Imogene both have serious exposure .. especially Black Bear with it's hairpins into Telluride. You should be able to make it stock if you're careful (both are rated a 4/5 out of 10). But if you're not comfortable with your truck, and shelf roads and 500 foot drops, you might want to look somewhere else.
Engineer is a great one. Spectacularly beautiful. Takes you to Animas Forks (great historic ghost town above Silverton). Mostly non technical (rated 2/3). Goes between two of the best towns in the San Juans (Lake City and Silverton).
Tincup Pass in the Collegiates is another great one that takes you to some historic ghost towns. Also rated 2/3.
It's not too bad driving from Ouray up to Yankee Boy Basin on the back side of Mt Sneffels either. Another remarkably beautiful run.
